organic compounds form lengthy chains and bonds — functional groups —————– aldehyde (-CHO) ,, alcohol(-OH),,, ,ketones,, carboxylic acids BASED ON NO OF CARBON ATOMS — 1C- methyl 2C - ethyl 3C - propyl 4C - butyl 5C - pentyl (5 symbols – placed linearly)

• Carbohydrates (Polysaccharide )
  • Disaccharides
    • Monosaccharides (Glucose )

the number glucose is a hexose — with 6 carbons (the smallest unit of carbohydrates = 6 glucose) Natural saccharides are generally built of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more.
